I am tempted to get a pair of these but am wondering if they would work well with the amp in the Xonar DG, I would pretty much leave these plugged into that 24/7.
Also how is the sound signature compared to the Sennheiser HD-25 II? I want something different honestly, but still very detailed, maybe smoother, I was looking into the Samson SR850 but these seem like they might be the better buy, I would use them mainly for gaming which I thought opened might work better for but I hear the sound stage was rather good on these also and they look very comfortable, my ears are small so it should cover them totally.
Honestly, I don't find them to be terribly great for gaming as their soundstage really isn't great. However, they will pair with the Xonar DG nice enough.
